42T Garbaruk 1X N/W 10-46T Garbaruk Cassette XTR Di2 rear mech
I'd add that with GarbarUK cage on XT mech you can go all the way to 52t at the back, I have this one my gravel bike.
Garbaruk cage on a 11 speed GRX rear mech will happily shift a 50t cassette which is what I do on the gravel bike.
52t in the back??
